Available in PDF, EPUB and Kindle. Book excerpt: In 1982 the Iowa DOT allowed a successful bidder the option of submitting materials and proportions using fly ash to produce a portland cement concrete (PCC) paving mixture to meet a specified compressive strength. The contractor, Irving F. Jensen, received approval for the use of a concrete mixture utilizing 500 lbs. of portland cement and 88 lbs. of fly ash as a replacement of 88 lbs. of portland cement. The PCC mixture was utilized on the Muscatine County US 61 relocation bypass paved as project F-61-4(32)--20-70. A Class "C" fly ash obtained from the Chillicothe electric generating plant approximately 100 miles away was used in the project. This use of fly ash in lieu of portland cement resulted in a cost savings of $64,500 and an energy savings of approximately 16 billion BTU. The compressive strength of this PCC mixture option was very comparable to concrete mixtures produced without the use of fly ash. The pavement has been performing very well. The substitution of fly ash for 15% of the cement has been allowed as a contractor's option since 1984. Due to the cost savings, it has been used in almost all Iowa PCC paving since that time.

Book Synopsis Quality Control of Highway Concrete Containing Fly Ash by : Woodrow J. Halstead
Download or read book Quality Control of Highway Concrete Containing Fly Ash written by Woodrow J. Halstead and published by . This book was released on 1981 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report is essentially a synthesis of pertinent information concerning the use of fly ash as an ingredient in concrete for highway construction. It has been prepared to provide a basis for an adequate response by the Department of Highways and Transportation to requirements of the Resource Conservation and Recovery Act and the Environmental Protection Agency pertaining to the use of this by-product in concrete purchased with federal funds. Special attention is given to the quality control and acceptance problems associated with highway usage of fly ash concrete, with emphasis on problems relating to air entrainment. References to the background literature that established the suitability of fly ash as a pozzolan and its use in concrete are The requirements for fly ash as set forth in ASTM Specification C618 are reviewed and the- characteristics to be expected from concrete containing fly ash are discussed. It is recommended that the Virginia Department of Highways and Transportation permit the use of fly ash in concrete at the option of the contractor with prior approval by the state. It is also recommended that suitable specifications for this use be prepared following the guidelines previously recommended by the Concrete Research Advisory Committee.

Book Synopsis The Use of Class C Fly Ash in Highway Construction by : Ferguson, P. Joy
Download or read book The Use of Class C Fly Ash in Highway Construction written by Ferguson, P. Joy and published by . This book was released on 1990 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Much attention has been focused in recent years on conserving natural resources and energy. Numerous waste products and/or byproducts from various industrial and commercial processes, normally deposited in landfills, have been proposed for use as alternate construction materials. One byproduct that has shown considerable promise as an alternate construction material is fly ash when used in a lime-fly ash (LFA) base course. This paper describes the use of this waste product in LFA stabilized granular materials as an alternative to cement treated materials for base construction. The primary disadvantage of a cement treated base (CTB) is the environmental (shrinkage) cracking that leads to the infiltration of rain water and incompressibles, pumping of subgrade soils, spalling of the crack faces and other problems that adversely effect pavement performance. It has been shown that the slow strength gain associated with LFA leads to a condition where the microcracks in the material are generally healed before they can develop into macrocracks. Continued chemical reactions, known as autogenous healing, within the mix are largely responsible for this behavior.
Book Synopsis Low Cost Fly Ash, Sand Stabilized Roadway by : S. J. Klassen
Download or read book Low Cost Fly Ash, Sand Stabilized Roadway written by S. J. Klassen and published by . This book was released on 1986 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fly ash, a by-product of coal-fired electricity generating plants, has for years been promoted as a material suitable for highway construction. Disposal of the large quantities of fly ash produced is expensive and creates environmental concerns. The pozzolanic properties make it promotable as a partial Portland cement replacement in pc concrete, a stabilizer for soil and aggregate in embankments and road bases, and a filler material in grout. Stabilizing soils and aggregates for road construction has the potential of using large quantities of fly ash. Iowa Highway Research Board Project HR-194, "Mission-Oriented Dust Control and Surface Improvement Processes for Unpaved Roads", included short test sections of cement, fly ash, and salvaged granular road material mixed for a base in western Iowa. The research showed that cement fly ash aggregate (CFA) has promise as a stabilizing agent in Iowa. There are several sources of sand that when mixed with fly ash may attain strengths much greater than fly ash mixed with salvaged granular road material at little additional cost
